Conflict of Interest
3
• The Intersection of the Public Health System and Health Care
Delivery System
• Community Based Public Health Surveillance Projects
• Behavioral Risk Factor Surveillance System (BRFSS)
• Predictive Analytics for Lead Hazard Prevention
• Sexually Transmitted Infection electronic case reporting
• Future Directions
Agenda
4
• Recognize how disparate information systems from the public and
healthcare sectors can improve information sharing of disease prevalence
and can surface the needs of populations who are at highest risk due to
social determinants
• Describe how predictive analytics applied to public health can improve
clinical practice
• Discuss the value of leveraging data and partnerships to change the
current model of clinical care from being reactive to proactive in various
public health domains
• Identify public health functions and use cases that can integrate with
primary care workflows leveraging interoperable technology
• Evaluate opportunities within current practice to apply approaches
discussed in either primary care or public health settings
Learning Objectives

public health through innovative collaboration.

The Behavioral Risk Factor
Surveillance Survey (BRFSS)
15
History and background of the
BRFSS
• In 1984, the Centers for Disease Control and Prevention (CDC)
established the Behavioral Risk Factor Surveillance System
(BRFSS).
• BRFSS is the nation’s premier system of health surveys that
collect state data about U.S. residents regarding their health-
related risk behaviors and events, chronic health conditions, and
use of preventive services.

Data Across Sectors for Health:
Lead Prevention Project

21
Background: Lead Poisoning
• Imposes devastating health, social, and economic costs
annually
• Disproportionately impacts vulnerable populations including
those served by community health centers (CHCs)
• In Chicago, over 80% of housing was built before the 1978 lead
paint bans
• Nearly 2,000 children test positive for lead poisoning every year
• Silos of data on the prevalence of lead can impede efforts to
address social determinants of health

with a low opportunity index are
5x more likely to have an

Innovative Collaborations:
Electronic Sexually Transmit
Case Reporting (eCR)
29
Background: Burden of STIs in Illinois
Case Counts of Gonorrhea:
• 13,608 (Cook County, 2015)
• 17,130 (Illinois, 2015)
Case Counts of Chlamydia:
• 41,056 (Cook County, 2015)
• 69,610 (Illinois, 2015)
30
Problem Statement:
Case Reporting is Manual and Time Consuming leading to
Inaccurate Disease Surveillance

Next Steps/Recommendations
• Collaborate with IDPH/CDPH to receive eCRs
and onboard into their surveillance system
• Revise data to capture in the eCR
-Medications administered at the follow-up
treatment visit
-Medications prescribed at the follow-up
treatment visit
-Other follow up (e.g., partner screening referral)
